SPECIFICATION forming part of Letters Patent mfeee eanated August 1, 1899. Application filed October 22,1897". ESerial No. 656,030. (No rnodel.)

To all whom it may concern:

zen of the United States, residing at Fair For est, in the county of Spartanburg and State of South Carolina, have invented a new and useful Windlass Water-Elevator, of which the following is a specification.

My invention relates to well-fixtures, and particularly to a Windlass water-elevator, and has for its objects to provide a simple, inexpensive, and efficient construction and arrangement of parts wherein the receptacles; are arranged to counterbalance each other,

and to provide an improved stop mechanism for maintaining the parts in the desired positions.

Further objects and advantages of vthis invention will appear in the following description, and the novel features thereofwill be particularly pointed out in the appended claims.

In the drawings, Figure l is a ferred form of bucket and bucket-tiltin g de Fig. 6 is a detail view in perspective vices. of a portion of the preferred trip-bail.

, Similar numerals of reference indicate corresponding parts in all the figures of the draw- I p 7 7 full and dottedjlines in, Fig. The detent ings. H

Mounted in suitable hearings in the sup; porting-frame l is awindlass having a drum 2 and -an'operating crank or handle 3, said drum being traversed by a continuous chain at, terminally supporting receptacles or buck ets 5 and engaged by the sprocket teethof the drum.

Arranged contiguous to the paths of the buckets is a trough'or receiver 6, having a suitable outlet 7,and contiguous to this trough is mounted a swinging trip-bail 8, of which the longitudinal bar extends continuously from one end of the trough to the other for engagement by trip-fingers 9"on"the upper V perspectiv View of a water-elevator constructed in ac- Fig. 5 is a vertical sectional;

construction illustrated these trip-fingers are curved inwardly'or over the buckets at diametrically opposite points midway between the points of attachment of the bucket-bails 10, and the trip-bail, which inclines down- Wardly when inits normal position, is adapt-ed to swing upwardly over the contiguous edge of the trough when engaged by the trip-finger of a bucket to cause the tilting of the bucket to discharge its contents into the trough, as will beseen by reference to Fig. 2,

p The drum is provided with an attached clutch-ring 11, provided at its inner periphery with angular clutch-teeth 12, a guide-groove 13 being formed parallel with the plane of the clutch-ring to separate the series of clutchteeth from the plane of the contiguous body portion ot the drum. Ooiiperating with the clutch-ring is a pawl 14, pivotally mounted I edges of'the walls of the buckets. In theat its lower end upon the frame and provided at its free end with a double-beveled or rounded detentlo forengagementwith the clutchiteethfu This pawl in order that it maybe interlocked; with the drum to prevent transverse displacement is provided with a guidecar 16, arranged in the plane of the said groove of the drum and projecting beyond the opposite sides of the pawl to lit in said groove, and

the pawl is adapted'to be yieldingly held by r y in an in ned re ide it r i ihe right or to the left, as shown, respectively, in

is square at its outerside an djis double-beveled'or, rounded at its inner, side, whereby when the pawl is in thepositionindicated in cated in dotted lines in Fig. 3 the drumjis adapted to rotate in the opposite direction to that indicated by the arrow. Thus the drum may be locked in a position eanerprthe buckets elevated, and the manipulation of the pawl is facilitated bya terminally-headed thereby holdthe pawl in operative engage- V nient withfthe: clutch-teeth; The pivotal point otthe pawl is approximately inthe ver- A tical plane of the axis ofthe drum, whereby stem 17, which projects through a slot 18 in the frame of the apparatus within reach of the operator.

From the above description it will be understood that in addition to the facility afforded by the clutch mechanism for controlling the position of the drum, and hence of the elevating receptacles or buckets, the manner of supporting the buckets provides for a counterbalanced operation of the mechanism and at the same time provides for increased durability by reason of the continuous-chain connection.

In Figs. 5 and 6 I have shown a pump mechanism constructed in accordance with my invention in so far as the operating mechanism is concerned and illustrating a preferred construction of bucket and tilting devices, wherein the bucket 5 is provided at an intermediate point approximately one-thi rd of the depth of the bucket from its top with a transverse bar 10, through a-central opening 10 in which extends a hoisting-cable 4, in this case consisting of a rope. The bucket is flared toward its top and is provided with an inturned rolled npperedge 9, constituting an engaging flange or rim for contact with a forwardly and downwardly inclined hook 9" on the trip-bail 8. This trip-bail is mounted contiguous to a trough 6, into which the contents of the buckets are adapted to be discharged, and the swinging movement of the bail is limited by suitable upper and lower stops 8" and 8 Inasmuch as the preferred form of bucket is axially connected with the hoisting-cable at an intermediate point of the depth of the bucket, it will be seen that the engagement of the rim 9 of the bucket with one of the hooks of the trip-bail will cause the prompt tilting of the receptacle, and, furthermore, that-twisting of the cable will not affect the efficiency of the engagement of said rim with the trip-bail. In other words, the engaging rim being' continuous it will be engaged by the hook or projection 9 of the trip-bail, whether the twisting or untw'isting of the cable causes rotation of the bucket ornot. The attachment of the hoisting-cable to the bucket I is preferably obtained by means ofa button or disk 10, arranged in contact with the under side of the cross-bar 10*, and the drum 2 is provided, to suit the cable, Witha cross-sectionally-V-shaped seat 2", into the apex of which the cable is crowded to prevent slipping/of the cableo er the drum.

In practice the trip-bail is preferably f ulcrumed at an intermediate point of the depth of the trough, whereby as the bucket rises after engagement with the bail its engaged edge is drawn inwardly over the edge of the trough, and finally after the arm of the bail comes in contact with the upper stop 8 the strain upon the cable applied by the hoisting devices turns the bucket to arrange its upper edge approximately in .alinement'with the draft of the cable, and thus discharges the contents of the bucket, the lower edge of the on the edge of the bucket, for the reason that by so doing I can cause the necessary lateral movement of the bucket to carry its discharging edge over the contiguous edge of a trough or receptacle without carrying the bucket any considerable distance above the trough or receptacle. As shown in the drawings, Fig. 5, the stop 8 limits the upward-swinging movement of the trip-bail immediately after the discharging edge of the bucket has reached a point slightly above and suitably over the edge of the receptacle or trough, thus avoiding lost motion and unnecessary elevation of the bucket.

The construction of clutch and operating mechanisms is identical with that herein-before described, the pawl 14: being pivotally mounted at a point vertically under the axis of the spindle of the drum and being adapted for lateral adjustment at its upper free end for engagement with the clutch-teeth 12 in order to lock thedrum against rotation in either direction at the option of the operator.

From the above description it will be seen that, particularly in the preferred construction of tilting devices illustrated in Figs. 5 and 6, the bucket is provided with an inturned beaded edge which projects inwardly beyond the planeof the inner surface of the bucket to form a pronounced projection adapted to be engaged at any point by the hook of. the trip-bail, and that this inturned rim or bead serves as a bearing-point for the intermediate portion of the hoisting-cable when the bucket is in its tilted position to prevent chafing of the cable, said position of the parts being indicated in full lines in Fig. 5. Thus theinturned beaded edge of the bucket performs the function not only of engaging positively with the hook of the trip-bail, but of a bearing for the cable at a point diametrically opposite to that of the engagement of the tripbail hook therewith.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is-- 1. In an apparatus of the class described,the combination with a Windlass having a drum mounted for rotation in opposite directions, and buckets carried by opposite ends of a ..cable traversing the drum, of an internally ICO clutch-pawl pivoted upon a supporting-frame 1 opening, a hoisting-cable terminally extended eccentrically with relation 'to and vertically beneath the axis of the drum and terminally constructed to engage the teeth of said clutchring at either side of the plane of the axis of the drum, said clutch-pawl being held by gravityin either of its adjusted positions and having an interlocking connection with said clutch-ring in each of its adjusted positions, to prevent transverse displacement of the pawl with relation to the clutch-ring, substantially as specified.

2. In an apparatus of the class described,the combination of a bucket-supporting drum having a concentric internally-toothed cl utchring and a contiguous guide-groove, a reversible clutch-pawl having a detent provided with a double-beveled or rounded face at one side, and adapted to engage the clutch-teeth at either side of the plane of the axis of the drurh, and a guide-ear extending in opposite directions from the detent and fitting in said guide-groove of the drum in either position of the pawl, substantially as specified.

3. In an apparatus of the class described,the combination of a bucket having an unobstructed beaded upper edge consisting of an V inwardly-rolled portion of the side Wall of the bucket, a transverse bar arranged in the bucket between the planes of its inturned rim and bottom and provided with a central through said opening of the bar and provided below the plane thereof with a stop to prevent upward displacement, means for operating the cable, and a swinging trip-bail provided with a downturned hook overhanging the path of the upward movement of the bucket, and adapted to engage said inturned rim at any point of the length thereof, the hoisting-cable, in the tilted position of the bucket, being arranged in contact with the beaded edge at a point diametrically opposite to the point of engagement of said hook, substantially as specified.

4. The combination of a bucket having an inwardly-beaded upper edge, aflexible hoisting-cable having a swivel connection with the bucket, upon an axial line below the upper edge thereof, means for operating the cable, and a swinging trip-bail pivoted out of the path of the bucket and having a hook to engage the bead at the upper edge thereof, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
